i always keep my weapon updated and i never had any problem with accuracy.
also, keeping the dex capped helps. :3

for the advanced / combo class discussion, i'd like to see my beloved samurai back, and hopefully my profency with lances won't go waste, as they'll be able to use lance/spears as they did in XI.
also a lancer spec like there used to be in FFT wouldn't hurt: a pure knight with heavy armor and halberds, with jump of course. can't wait to see my wee-legs springing me to the moon.
